To all whom it may concern:

Be it known that 1, JAMES A. KEYEs, a citizen of the United States, andresident of the city, county, and State of New York, have made certainnew and useful Inventions Relating to Presses, of which the following isa specification, taken in connection with the accompanying drawings,which form a part of the same.

This invention relates to presses and relates especially to powerpresses for the production of cakes of soap or other articles.

In the accompanying drawings showing an illustrative embodiment of thisinvention, and in which the same reference numeral refers to similarparts in the several figures, Figure 1 is a plan view. Fig. 2 is alongitudinal section taken along the line 22 of Fig. 1. Fig. 3 is anenlarged top view partly in section showing the dies and die plunger.Fig. 4 is a similarly enlarged view showing the parts in a differentposition. Fig. 5 is an enlarged side view showing the feeder grips. Fig.6 shows the finished soap cake. Fig. 7 is a detail showing the. springdetent. Figs. 8, 9 and 10 are enlarged views showing the feeder indifferent positions.

In the illustrative embodiment of this invention shown in the drawings,the heavy frame for the operating parts of the machine may be formed bythe members 1, 2 connected by suitable transverse braces and havingbearings 5, 6, in which the drive shaft 4 having the pulley 3 thereonmay be mounted. The bevel gears 9, l0 drive the cam shaft 12 from thedrive shaft, this cam shaft being mounted in suitable bearings 11 on theframe and carrying the cams 13, 15, as well as the pulley 120 whichoperates the discharge belt 121. The table 95 may be provided withsuitable adjustable guides 88, 90 and with an aliner 122 by which thearticles may be properly fed in connec tion with the supply belt 89, ifdesired. This belt is mounted on a loose pulley 92 on the shaft orconnector 93 and is driven by the pulley 91 mounted on the stub shaft101 and driven by a sprocket chain 99 from the intermediate shaft 123which carries the spur gear 98 meshing drive shaft 4.

The articles fed into the press against the aliner 122 may be fed alongto the dies or other compressing apparatus by a suitable feeder 23 whichmay be mounted in bearings 26 at one side of the machine and in thebearwith the gear 97 on the ing 100 supported in the bracket 96 at theother side. This feeder may be given a reciprocating movement by thelink connected with the collar 29 on the feeder and pivoted at its otherend to the lever 14 having a suitable follower 125 to engage a camgroove in the face cam 13. It is also preferably given an oscillatingmovement at the same time by forming the feeder end 24 polygonal toproperly engage the sleeve 28 aving a suitable collar 27 between the twobearings 26. The arm 25 on this sleeve 28 may carry a suitable follower124 to cooperate with a cam groove in the cam 15 so that the feeder arms20, 21 adjustably secured on this feeder may be raised by oscillatingthe feeder, then reciprocated rearward, then swung down to engage ablank and reciprocate with the same forward to bring the blank intocodperation with the dies. The detacher 103 may also be adjustablymounted on a similar arm 102 on the feeder, as indicated in Figs. 1 and8.

The feeder arms 20, 21 may be formed as indicated in Figs. 8, 9 and 10and com rise suitable pins 67, 68 to which the heats 22 carrying thegrips 69, 70 are secured, for instance by the projecting studs 71, 72. Asuitable spring 111 may be used to force the grip 7O inward and thisspring may be secured to the collar 110 on the pin 68, and at its otherend to a suitable detent sleeve 112 which cooperates with a detent 113mounted in the arm so as to cause the desired intensity of springaction. The lever 109 is mounted on the inner end of the pin 68 and itsupper end 31 co6perates with a suitable adjustable stop 108, as seen inFig. 9. This lever engages at its lower end the cam 96 so that duringthe rearward movement of the feeder the lever and grip 70 are swungupward away from the corresponding grip, as 69. When the feeder comesinto its extreme rear position as in Fig. 8, it is oscillated so thatthe grips swing downward on either side of the article 62 and then whenthe feeder again moves forward the lever rides over the projecting endof the cam 96 so as to gradually swing downward and engage the forwardend of the article, force it rearward against the grip 69 and grip it inconnection therewith.

As indicated in Fig. 1, the drive shaft 4 may carry two cams 7, 8 inopposite phase to actuate the connectors 104, 104, which as indicated inFig. 2, are pivoted to the lugs 106, 107 on the two slides 18, 19. Theslide 19 may be formed with the slide head 75 to which is secured theplunger 76 carrying in its forward end the die 64, which of course, mayhave a working face of any desired shape. The releasers 73, 74 havingdownwardly inclined cam faces may be mounted on either side of thisslide head so as to engage the studs 72 and swing the grips apart out ofengagement with the blank as the slide moves forward, see Figs. 1 and 2.A cylindrical ejector 63 may be mounted within the die and plunger andnormally pressed forward by a spring 85 acting between the bracket 87and the set nuts 84 on the ejector, as indicated in Fig. 1. A suitablealiner 86 in this bracket cooperates with the end of the plunger 63 soas to properly aline its forward end with respect to the die 64. Thedetent 83 may be pivoted in the frame so that its end cooperates withthe collar 126 on the ejector, as is seen in Fig. 1. The other end ofthis detent is engaged by a suitable strong spring 79 mounted in thebracket 81 and operating to force the end of the detent against the adjustable sto 77 mounted in the lug 78. The slide 18 may be provided withthe slide head 65 to which the die casing 34 may be secured in anydesired way as by the bolts 66. The plunger 35, to the outer end ofwhich the rear die 33 may be secured, asses through the slide head andalso throug the slide yoke 40 secured to the slide, the fork 39 beingsecured to the plunger to the rear of this slide yoke. The ends 41 ofthis fork cooperate with the adjustable stops 42 mounted in brackets 44secured to the machine frame and rigidly held in adjusted position bythe set nuts 43. In this way, the forward movement of the lunger andrear die 33 is positively limite The plunger 35 is normally pressedforward by spring action which may involve the primary spring 37operating be tween a suitable adjustable abutment 36 on the plunger andthe forward end of the slide yoke. At the time when the final compression takes place a secondary spring may also be brought into operation,if desired, by using the spring sleeve 45 which, as indicated in Fig. 1may be mounted loosely within the slide collar 48 secured to the slide18 below. The forward movement of this spring sleeve may be limited bythe ring 46 and the secondary spring 47 engages and presses this springsleeve forward, the annular collar stop 48 being adjustable within thecollar to secure the proper intensity of this spring action. A similarcylindrical ejector 32 may be mounted within the plunger 35 and providedwith the set nuts 50 on its rear end to limit its forward motion withrespect to the plunger. Its extreme rearward movement with respect tothe plunger may be accurately limited by the adjustable aliner 41mounted in the enlargement 49 of the plunger soas to properly cooperatewith the lug 53 secured to the ejector which is normally pressed forwardby the spring 52 acting on this lug. The detent 54, Figs. 3 and 7,cooperates with this lug to retract the ejector overcoming the spring 52which normally tends to protrude it. This detent may be mounted on thestud 61 in the frame and normally pressed toward the lug by a suitablespring 60 having one end engaging the detent and the other end securedto the pivoted spring clip 59 which is engaged by a suitable adjustingscrew 58 to adjust the intensity of this spring action, which should besufiicient to overcome the spring 52. The distance piece 56 is mountedon a suitable extension 57 of the slide and is adjustable so as toproperly engage the tail 55 of the detent 54 so that the other end ofthe detent engages the lug 53 at the proper time.

During the operation of the press, the blanks 62 are engaged by thegrips 69, at the proper time and fed forward while held between thegrips so as to be brought accurately between the dies 33, 64. At thattime, the slides approach each other and the ejectors come together,engaging the blank on either side so as to hold it between them, as isshown in Fig. 3, the inward movement of the ejectors being adjusted soas to give the desired intensity of this gripping action. Then thefurther movement of the slide 19 brings the releasers into engagementwith the studs 71, 72 so as to wedge the studs upward and swing theconnected grips apart away from the blank held by the ejectors so thatthe feeder may be swung up and moved backward to engage another article.Then as the slides move together still further the fork 39 may come intoengagement with the stops 42, preventing further forward movement of therear die '33. As the slide 19 moves forward from the position indicatedin Figs. 1 and 3, the strong spring 79 causes the detent 83 engaging thecollar 126 on the ejector 63 to overcome the action of the spring 85 andgradually force the ejector backward with respect to the plunger and dieuntil when it comes into engagement with the aliner 86 this ejector isaccurately flush with the die 64 as indicated in Fig. 4 and heldaccurately in that position. The forward movement of the slide 18 movesthe distance piece 56 so that the detent 54 is swung around and retractsthe lug 53 and the connected ejector 32 so that the outer end of thisejector is gradually withdrawn until it is brought and held accuratelyflush with the working face of the die 33, as is indicated in Fig. 4,and maintained in this position by the aliner 51 engaging the lug 53.The ejectors during these relative movements maintain their grip on theblank 62 and support the same symmetrically with respect to the dies.

The forwardmovement of the slide 18 carries the slide head and connecteddie casing 34 forward so as to inclose the blank 62 and when the twodies 33, 63 engage the blank the further movement of the die 64 pressesthe die 33 and its plunger backward against the action of the primaryspring 37 so that the blank may be gradually and symmetrically expandeduntil its edges engage the die casing. At this point the secondaryspring may be brought into action to increase the resistance to thefurther rearward movement of the rear die, the plunger abutment 36coming into engag ment with the spring sleeve 45 at this time. A slightfurther movement of the 'front die 64 gives the final compression whichcompletes the forming of the article, the parts then having thepositions indicated in Fig. 4, this position being held while theeccentrics pass their dead centers. The slides thereupon move apart andthe slide 1'9 and front die 64 are withdrawn, moving out of engagementwith the die casing and the article, the springs pushing forward theplunger 35 and connected rear die 33 during this time until the rear dieis in about the position indicated in Fig. 3. The ejector spring 52 ispreferably so adjusted that the adhesion of the article to the face ofthe die 33 wher soap is acted on, is sufiicient to keep the ejector inits retracted position within the die so that its outer end is flushwith the Working face of the same, as indicated in Fig. 4, until the dieface is clear of the die casing. 'lhereupon the oscillation of thefeeder 23 brings the detacher 103 sharply into engagement with thearticle, as is indicated in Fig. 8, freeing it from the die face. Thenthe ejector springs forward under the action of its protruding spring 52so that the completed article is immediately forced away from the dieface and can be moved along toward the discharge belt by the grip 70,the slide 18 having sufficient rearward movement, if desired, to carrythe fork '39 clear of its stops and give ample clearance as the feederbrings forward a new blank between the ejectors.
